Premco Global has been correcting after the uptrend till around 1000. Now its at around the 61.8 percent retracement level
Based on Vol analysis its looks be in accumulation phase now ( marked inside the rectangle) and a reversal might be on the cards. RSI also rising
Also there is a double bottom on the daily chart

As can be seen from the Weekly chart, Tata motors has taken support above the double bottom neckline
Also it had taken support at the internal trend line inside the channel. Also RSI above 50. Looks poised for an up move in my opinion
This is just a view. Please do not base your trading decisions based on this.

Nifty has been forming a descending triangle on the 15 min chart .
Also it has not been able to break the resistance at 8820
Price suggests that 8700 is possible
Stop loss should be if it breaks out of the descending triangle on the upside
